PLZZZZZ HELPP How do you predict the bond length and energy would change if hydrogen formed a bond with Astatine (At)? ​
kkurt [141]

The bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order <u>increases</u> or <u>decreases</u> or when its potential energy is at the <u>lowest</u>.

<h3>What is bond length?</h3>

Bond length is also referred to as bond distance and it can be defined as an equilibrium distance between the nuclei of two (2) covalently bonded atoms in a molecule.

<h3>What is bond energy?</h3>

Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.

In Chemistry, the bond length and energy of a molecule is typically determined by the following:

  • The bond order or number of bonded electrons.
  • The potential energy possessed by the molecule.

In conclusion, you can predict that the bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order increases or decreases or when its potential energy is at the lowest.

A substance has a boiling point of 78 °C. Which of the following is true about the substance?
laila [671]

Answer: C; it will also change from a gas to a liquid at 78°C while the gas loses energy.

Explanation:

Took the test. If it boils at 78°C, then that means it will be either a liquid turning into a gas, or a gas turning into a liquid. If the gas loses energy, that means it is being cooled, so if a gas loses energy at 78°C, it will become a liquid.
